- Abstract
In order to investigate the effect of different microbial feed additives on the meat quality of culled hens, a complete feed and four feeds mixed with different microorganisms were fed to culled hens to analyse their effects on muscle traits, nutritional composition and textural characteristics in each group. The results showed that the feed containing 2% Rhodotorula significantly increased the muscle redness and moisture content (P<0.01), while significantly reducing hardness (P<0.05); the feed containing 1% Bacillus subtilis significantly increased the muscle redness and crude fat content (P<0.01), and reduced hardness (P<0.05); the feed containing 5% Lactobacillus plantarum significantly increased the muscle redness and crude fat content (P<0.01) and reduced the crude protein content (P<0.05); the feed containing the three microbial complexes significantly increased the crude fat, essential amino acids, delicious amino acids and free amino acids content (P<0.01). In summary, microbial feed additives are able to modify the muscle redness of laying hens, with Rhodotorula exerting a greater influence on muscle moisture content as well as tenderness, and Bacillus subtilis and Lactobacillus plantarum contributing more to muscle nutrient content.
